Are people even voting honestly in this thread?

I'm getting really irritated at all the post I see that have pretty obvious faint lines and yet all these votes saying it's negative. I feel like some people are just voting negative in the polls to be mean and bring people's hopes down. I even posted a pic of my test and had a ton of negative votes and then reposted again later that night for more opinions and it switched to almost all positive votes. SAME EXACT PICS! I've also seen it the other way around with giving false hope on some test. Has anyone else noticed this?
